Hellenic Physical Society (EEF) is responsible for organizing all of the Greek teams that will represent the country.
Registration begins in August of each year after the problems are published. Students all over Greece can register and start working on the problems.
It is not necessary that a team consists of students from the same school. Students must be at the proper age, from 12 to 16 years old (High school students), both from private and public schools.
EEF is responsible for organizing the students in teams and help them through the problems.
Students of a different nationality that study in schools (private or public) in Greece have also the right to participate.
